Abstract
The present invention is to fabricate a quantum dot functional structure having ultra-fine particles homogeneously distributed in a transparent medium by efficiently fabricating high-purity ultra-fine particles having a single particle diameter and uniform structure and depositing the ultra-fine particles onto a substrate in conjunction with the transparent medium. For these purposes, an apparatus for fabricating a quantum dot functional structure is provided. The apparatus comprises: an ultra-fine particle generating chamber for generating high-purity ultra-fine particles by exciting a semiconductor target with pulsed laser light in a low-pressure rare gas atmosphere, and then by allowing the semiconductor target to be detached or ejected by ablation reaction and condensed and grown in the gas; an ultra-fine particle classifying chamber for classifying the ultra-file particles; a depositing chamber for depositing the high-purity semiconductor ultra-fine particles and the transparent medium by exciting a transparent medium target with excimer laser light at the same time or alternately when the high-purity semiconductor ultra-fine particles are collected onto the substrate, and by collecting the substance generated through ablation reaction onto the substrate; and a carrier gas exhaust system.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
